1 Re contradictory: what you wrote to Georgina was: "It seems Paul has a different definition of 'subjective' to it's common use in science, which is implicit from his essay, appearing wholly contradictory but obviously not as understood by Paul, so apparent directly conflicting views may not really be so"
2 Re Edwin's view: I do not care who's view you defer to, what I do care about is that any point is properly substantiated, and not an assertion. But you do not substantiate this either.
3 Re subjective: the full sentence is: "So knowledge thereby gained is not inherently subjective, since it represents, for us, both what is, and all there can be". That caveat 'for us' does not make it subjective, as you assert. Because if you re-read paras 3-5, you will see that 'for us' refers to the knowledge of reality, ie what it is possible for us to know. Which is based on a physical process. And is reality, we do not have access to 'something else'. We can of course hypothecate, otherwise we would be very limited. But that is based on, and referenced to, validated direct experience. In simple language, we cannot transcend our own existence, that is what beliefs do, and this is science. So there is a valid and inevitable closed system (it is a function of the sensory systems), within which objectivity is establishable. "If 3 people observe an event from different places or in different states of motion, they will all see something different. That is 'subjective' reality." No it is not, they are perceptions, which could be objective or subjective, within their own contexts. And anyway, as I make perfectly clear, I am not interested in anything after point of reception at sensory system. "The words do not then get that across" because you are interpreting what I write, rather than reading what I actually write.
4 Re presence: I did not like that word myself, that is why it is in parenthesis (in fact it has gone in the update). However, it is clear what I am referring to, and I do not care who else has used it in other contexts. We are supposed to be assessing what I have written. Neither do I care what maths does, and your references to zero, which are nothing to do with what I have written. I write of the concept of 'occupying' a configuration of 'spatial points', ie it is a method for expressing relative size/shape of physically existent phenomena. By definition, the smallest elementary particle will equate with a spatial point, it will 'occupy' a 'spatial point'. [Just for the record there can be no zero or infinity in physical reality, in the sense that zero means nothing, and a physical phenomenon is something, and physical reality has definiteness (it may be immense but not infinite)].
5 Re effects: Again, you have not read what I have written. I use different labels here, which are defined, so that the grammar does not become plain intolerable. The effects, are physically existent phenomena (aka light, vibration, etc), ie they are a reality. They result from an interaction between other physically existent phenomena, one of which is the reality we are trying to identify. It has nothing to do with sunglasses, you are referring to the wrong interaction.
6 Re observation: yet again, this is not what I an referring to. I am not interested in all that which goes on after reception at sensory system, please read para 17.
7 Re "Sorry to go on so long!" Not at all Peter. You are the first one who has made what I feel is a genuine attempt to understand what I am saying, and commented as such, and not just said tried to link what is apparently being said with their own efforts. Frankly, I have found most of the discussion intellectually dispiriting, a form of yes it is/no it isn't. What I will say, is that, obviously, I can only use the language available and that relates to another way of looking at things. But there is nothing fundamentally wrong with my use of language, my current amended copy has not changed much at all. So, all I can say is try it a couple of times more (its only paras 3-24), but, and I am not being rude here, just read what is there.
